(να δω ποτε θα βαλετε κανα λειτουργικο της προκοπης )

It’s been a while since I’ve posted a new build. A lot has changed in the code, but the single biggest visible change is the addition of protected mode emulation. It’s very far from complete. Right now, I’ve only gotten two protected mode games to work: Doom and Rise of the Triad – even so, those only work correctly if you disable Sound Blaster sound effects. Why those two games? I just happened to have them on my hard drive. Here’s the complete change list:

* 16/32-bit protected mode support added (no actual paging or protection works yet though)
* Fixed consistency issues with 16 vs. 32 bit stack and instruction pointers
* Fixed 32-bit addressing modes
* Small Sound Blaster DSP fixes, still lots of playback issues though
* Added support for a few FPU instructions
* Added extended memory support (XMS)
* Most instructions now work with 16 or 32-bit operand sizes
* Fixed a few issues that caused hardware interrupts to get disabled when they shouldn’t
* Eliminated generation of multiple identical operand decoders (reduces memory usage, may increase performance somewhat)
* Fixed an issue with unchained 256-color (mode X) display modes sometimes getting rendered incorrectly

If you’re expecting your favorite 32-bit DOS game to work now, you’ll probably be disappointed (unless, of course, you wanted to play Doom with no sound). Also, performance is not all that great for 32-bit programs, as I haven’t really optimized it for speed yet. I’m going to focus on improving protected mode compatibility up through version 0.6; expect all of these things to gradually improve from here.

Changes :
* Fixed memory leak when launching more than one program without restarting Aeon in between
* Minor performance improvements
* Lots of DOS process management fixes
* Command interpreter is now less of a kludge and uses interrupt-driven I/O like everything else
* Added configuration support and configuration editor – not complete yet
* Can now change drive mountings while emulator is running (with sometimes disastrous results – use only for disk swapping!)
* Integer divide-by-zero CPU exceptions now handled more efficiently
* Added command prompt change current drive command
* Added some primitive MSCDEX support – a _few_ CD-based programs may work now
* Fixed bug in LMSW instruction
* Fixed bug in DOS get file attributes function
* Added support for launching DOS programs/configuration files via command line
* Fixed intermittent crashing due to bug in mouse driver callback
* Fixed some issues with how Aeon handles invalid MS-DOS file names
* Lots of internal code cleanup and refactoring

CGA mode is forced to be blitted even if you have selected
Direct mode. I believe the blitted mode is fast enough for all
CGA games, and removing the direct mode made the code smaller
and simpler, and there is no danger of the game stopping because
of an unsupported CGA graphics opcode any more.
TEXT mode is now also using a blitted screen copy method with
a dirty buffer, so it is reasonably fast, and it too supports
now all possible opcodes to access the display RAM.
About a dozen new EGA opcodes added.
About a dozen new DOS interrupts are supported, including
some DOS internal functions that are needed by software like
Norton Sysinfo, and old FCB file functions that are needed by
very old games like Ultima 3.
Fixed bugs in "!" key, DOS memory resize function, division opcode,
and 0xE000 segment memory access when not mapped to an EMS page.

I’ve fixed a couple long-standing bugs and added support for some features I’ve been wanting to get in here for a long time – SVGA and the PC speaker. Also new to this version is the ability to mount CD ISO files and virtual floppy disk image files directly thanks to the excellent DiscUtils library. This is also the last version of Aeon that will target .NET 3.5; with .NET 4 scheduled for release on April 12, all future builds will require that version.

* Internal code refactoring
* Fixed expanded memory page aliasing bug (Star Trek: 25th Anniversary)
* Added PC speaker emulation (tones only, sampled playback won’t work)
* Added support for changing the character set
* Added support for 8×14 character resolutions in text modes
* Support for mounting disk image files (vfd, iso)
* Fixed a nasty bug in the PIT which caused random timing-related crashes
* Partial VESA VBE 1.2 implementation – some SVGA games will work (Master of Orion II, Lords of the Realm II both tested)
* Fixed a Sound Blaster detection bug

Changes :
* Fixed long-standing issue with the InterruptEnable flag not always getting reset after a system call
* Enabled UI elements for configuring emulated hardware
* Fixed minor bug causing too many bytes to be loaded from exe files
* DOS IOCTL Get Device Info function is more accurate and less of a hack
* Fixed another bug with handling invalid DOS file names
* Fixed bug preventing DOS FindFirstFile function from returning certain directory names
* Fixed bug causing child DOS processes to sometimes inherit the wrong environment block
* Fixed bug with some special DOS devices not being recognized (NUL, CON)
* Improved VESA VBE 1.2 implementation
* Partial VESA VBE 2.0 implementation
* Added AAM instruction
* Fixed improper Trap Gate emulation on interrupts
* General Protection Faults are now properly raised when an invalid selector is loaded
* Fixed stack alignment bug from an exception on a pop to segment register instruction
